SPRAY-BURNER.

To all whom it may concern:

Be it known that I, ARCHIE T. Rice, a. citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Spray-Burners, ofwhich the following is a specification.

This invention relates to oil burners used in connection wit-h fuel oilfurnaces in which the oil is atomized by an agitator, then forced intothe burners, where the hydrocarbons evolve combustible gases which, whenheated to incandescence, form the fiame.to be used.

The principal object of this invention is to provide improved means foruniting the hydrocarbons of the fuel with the oxygen of the air that isforced into the furnace through the burner from the bellows or othersuitable pressure supply. p

\Vit-h these and many other objects in view which will morereadilyappear as the nature of the invention is better understood,

the same consists in the novel construction,

combination and arrangement of parts as hereinafter will be more fullypointed out, illustrated and claimed.

in the accompanying drawings Figure 1 is a longitudinal sectional viewof the improved burner showing the combined cylindrical and cone shapedsections of the burner. Fig. 2 is a section taken on the line -2-2 ofFig. 1. and shows the air motor for Fig. 3 is a view taken on the line3-3 of Fig. 1, and shows the oil agitator inverted, the same beingdriven by the air motor shown in Fig. 2.

Similar nmncrals refer to corresponding parts throughoutthe severalfigures of thedrawings. Referring to Fig. 1 of the drawmgs, tlfe airfrom the bellows enters the burncz I through the pipe 10 while air underhigher pressure is forced through the pipe 11, thus Specification ofLetters Patent.

into a foam or spray, thus breaking the oil globules up into atoms andin this state conducted by the pipe 16, through the opening 17 into thewide mouthed cylindrical focusing chamber 18, which is preferablysuspended on the longitudinal center line of the main blast pipe 19.

The forward end 20' of the chamber 18 is contracted so as to insure eachatom of the oil striking the diverging cone or spreading element-21,which is attached to the upper side '22 of the focusing chamber 18, by abracket 23, as shown in F ig'. 1 of-the drawings. The finely divided oilleaving the outer periphery at the be so of the cone 21 is mingled withthe air, from the bellows or other'pressure supply, which is brough tothe burner through the pipe 10. The hydrocarbon of the fuel oil, unitingwith the oxygen of the air, forms a combustible mixture, which whenignited is heated to producing a clean flame of high temperature.

The auxiliary funnel 2 1 is a frustum of a cone the base 25 beingattached at its upper face to the inside of the blast pipe 19 while itslower ed e is free from the pipe thus allowing a 521st of air tocontinually pass between theinside of the blast pipe and the outside ofthe base of the frustum, through the opening 26 as shown in Fig. 1 ofthe drawings. It isthus seen that any oil adhering to the auxiliarycon'ewill bepic-ked up by this current and carried into the zone ofcombustion, thus obviating the loss of any 'fuel oil that is so commonthe ordinary types of oil furnaces.

Without further description it is thought that the many advantages ofthe herein described invention are readily apparent.

I claim:

1. An oil burner comprising a blast pipe, fuel focusing and mixingelements within the blast pipe an oil agitator, an air motbr having anoperative connection with said agitator. means for supplying oil to thesaid, agitator, means for conducting atom izcd oil from said agitator tosaid elements within the blast pipe, and means for feeding air underpressure to said air motor.

2. An oil-burner comprising a blast pipe, means for feeding air underpressure to said fuel focusing and 'mixmg elements within air motor. 10.the blast pipe, a bladed rotary oil agitator, a In testimony whereof Ihereunto aflix my rotary air motor ha ling a direct s aft consignaturein the presence of two Witnesses. nection with saii agitator, means forsup- ARCHIE T.
